The woman operative, who shall have to be known as Miss Clarke, prepared for her part with the greatest care. She even perfected herself in the charming Southern dialect so that she should be immediately taken for a daughter of the Sunny South. It was probably a week after the Mosby raid that a fine-looking and apparently embarrassed woman arrived at Fairfax Court House. Finally she managed to enlist the attention of the young woman who was known all through the transaction as “F.” The stranger, with feminine impulsiveness, gave her complete confidence to “F.” She said that she was greatly attached to the Confederate cause, that she was really a friend and an agent of the South and that she wanted advice and assistance in an effort to reach Warrington. “F,” who was the spy that had betrayed Stoughton to Mosby, literally received the newcomer with open arms. She took her to her own home where she was given a warm reception. Miss Clarke was given a repast which included corn muffins, and when they were placed before her she exclaimed: “This makes me feel that I am home again in the good old South. It has been terrible to have to live in the North with those Yankees. I have never seen a corn cake since I left the Virginia line.” Everybody laughed at this and everybody was happy. It really seemed like a family reunion. The visitor was petted and patronized and made to feel that she was a person of great importance. And why not? Wasn’t she engaged in carrying dispatches to the leaders of the Confederacy—dispatches which might result in the downfall of the Yankee Government? They forebore to ask her the nature of the confidential information which she claimed to be taking to Warrington. Naturally she would be reluctant to impart that even to such good friends as they had shown themselves. How did Miss Clarke feel under these circumstances? Did she have qualms of conscience at the thought of eating the bread of the family she might soon be called upon to denounce? Not in the least. She knew that the young woman before her had already betrayed the Union soldiers from a sense of loyalty to her section, and Miss Clarke did not have the slightest compunction about betraying “F” in turn. But the thing was to get the proof. She could give evidence that the family of “F” sympathized with the Confederacy and was willing to do anything to aid them, but that was not sufficient for her purpose. How could she get evidence—documentary evidence if possible? The answer came quicker than she had hoped for. “F” invited her to her bedroom, and when they had closed the door said to the visitor, “I have something I am going to show you. I think it will interest you for we are engaged in the same cause.” [Illustration: MAJOR-GENERAL J. E. B. STUART] With that she reached under the mattress and brought forth a document which she handed to her visitor. Miss Clarke read it with glowing eyes. It ran as follows:
